The vertices of triangle ABC are A(-1,-1) B(-1,2) C(6.0). What conclusion can be made about the angles of triangle ABC?
It's a multiiple choice question:
A) the measurement of angle A is equal to the measurement of angle B
B)the measurement of angle ABC is equal to 60
C) The measurement of angle A is equal to the measurement of angle C
D) the measurement of ACB is equal to 90
Clearly....D is not correct
And C is not correct....for angle A to equal angle C, BC would have to equal BA
And A is not correct, either....for angle A to equal angle B, BC would have to equal AC
To find the measure of angle ABC we can use:
arctan (7/2) = 74.05°
Mmmmm....doesn't appear that any of the choices are correct......here's a pic
